Why Won't The Java Upgrade Download On My Mac?

Installing Java into your browser doesn't necessarily install Java in Windows itself. How to install Java. Rather than allowing the browser to install Java for you because it says there's a plug in missing, go to Java.com and download the program there. It should install Java on your system as well as on every browser on your system. To enable Internet plug-ins, including Java, to load in Safari, check the Internet Plugins: Allow Plug-ins check box. Unlike Safari on Windows, there is no individual check box for Enable Java for Safari on Mac. When you encounter Java content in Safari, Safari will block the content from loading. Incomplete download and installation of the Flash installer program can also cause a computer to be unable to install Flash Player. Adobe Flash Player cannot install if a Web browser such as Internet Explorer, Firefox or Google Chrome is open, so be sure to close all browsers before trying to install Flash. Mac users installing or updating to the latest version Java are finding their shinies infected with the 'much loved' Ask Toolbar. This thing returns poor, ad-infested results, and silently changes.

If you've 'installed' Eclipse but are having trouble getting it to run, the most likely cause is that you have
 not correctly specified the JVM for it to run under. Doing so is easy, just read http://wiki.eclipse.org/Eclipse.ini
Exit Code 13
 64-bit Eclipse requires a 64-bit JVM, and 32-bit Eclipse requires 32-bit JVM--you can not mix-and-match
 between 32-bit and 64-bit. Mixing 32-bit and 64-bit versions is the most frequent cause of an Error 13, so
 make sure the version of Eclipse you installed matches the JVM/JDK that you're using to run it (especially if
 you are using eclipse.ini to specify the exact JVM used to run Eclipse, described 
above). If you are on a 64-bit operating system, the Eclipse 
 Installer will be looking for a 64-bit Java Runtime.
 As a test, open a command line window and run the intended java binary with the 
-d32 switch to test if it supports 32-bit, or -d64 to test for 64-bit support. It's often
 simplest to download a version of Eclipse that will work with whatever Java you already have installed.
 To check if you have a 32-bit Java Runtime.:
 To check if you have a 64-bit Java Runtime.:

Java 9, and later, with Eclipse versions prior to Oxygen.1a (Eclipse Platform 4.7.1a)
 Java 9 makes substantial changes as to how the classpath is handled in order to add modularity to
 Java. For most applications, this is invisible, but it creates issues for Eclipse's own modularity. Oxygen.1a
 is the first release of Eclipse that is ready to run under Java 9. If you still have an older Java runtime available,
 check the Running Eclipse reference documentation on using the -vm parameter to launch Eclipse and then update to a
 compatible version. If you must continue to use an older release, check the Wiki page at
https://wiki.eclipse.org/Configure_Eclipse_for_Java_9 for instructions on adding the 
 right startup parameters to your eclipse.ini file, script, or shortcut. 
 The current release can always be found at https://www.eclipse.org/downloads/ .[Updated on: Fri, 08 June 2018 16:29] by Moderator

macOS complains that Eclipse requires the legacy Java SE 6 runtime
 If you are trying to run Eclipse on a recent version of macOS, you might encounter an error message that
 advises you to install 'legacy' Java, with a link to download a very old version of a JRE (1.6). DON'T DO THAT.
 It turns out that Apple and OS X has done a thorough job of screwing up what used to be the best OS for 
 Java development. 
 The 'you need legacy Java' message was from macOS, not Eclipse. The advice to download and install it is 
 bad advice, but sadly nothing that Eclipse can remedy. Installing 'legacy Java' just reverts your system to a 
 VERY outdated JRE and renders much Java-based software, including Eclipse, broken. 
 Eclipse requires Java 8 or above, so the best thing is to download JDK 1.8 (not just the JRE) and install 
 that. In rare cases, you will need, or want, to point your eclipse.ini file to its exact 
 location per the instructions at the eclipse.ini wiki page. Oracle 
 JDK download links change often, so it's best to Google for 'JDK 8 download' and you'll find it. Here's the 
 page for Java 8 as it stands at the time I'm writing this. Here's the page for 
Java 9, which doesn't pose a problem for equally current versions of Eclipse. Here's the page for Java 10,
 which requires Oxygen.3a to support new language features.

This page describes how to install and uninstall JDK 8 for OS X computers.
This page has these topics:

See 'JDK 8 and JRE 8 Installation Start Here' for general information about installing JDK 8 and JRE 8.
See 'OS X Platform Install FAQ' for general information about installing JDK 8 on OS X. Free internet explorer download for mac.
System RequirementsObserve the following requirements:
Any Intel-based computer running OS X 10.8 (Mountain Lion) or later.
Administrator privileges.
Note that installing the JDK on OS X is performed on a system wide basis, for all users, and administrator privileges are required. You cannot install Java for a single user.
Installing the JDK also installs the JRE. The one exception is that the system will not replace the current JRE with a lower version. To install a lower version of the JRE, first uninstall the current version as described in 'Uninstalling the JRE'.
JDK Installation InstructionsWhen you install the Java Development Kit (JDK), the associated Java Runtime Environment (JRE) is installed at the same time. The JavaFX SDK and Runtime are also installed and integrated into the standard JDK directory structure.
Depending on your processor, the downloaded file has one of the following names:

Determining the Default Version of the JDKIf you have not yet installed Apple's Java OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app. See 'Note for Users of OS X that Include Apple Java 6 Plug-in'.
